The following is derived from the explanation of Function
14 in your ESI phone systemís Installation Manual or
Administratorís Manual (as the case may be).

Current ESI phone systems can be configured to reset
the time automatically when Daylight Saving Time (DST) ends or begins
each year. However, if your system is not configured that way (or
itís an older ESI phone system that doesnít perform the automatic time
change), the following instructions explain how to reset the time and date
manually.

Note:

To configure a compatible ESI system to change time automatically
when Daylight Saving Time ends or begins, see ďAutomatic adjustment
for Daylight Saving Time,Ē below.

On any ESI phone within the system, press PROG/HELP.

Note:

If using an ESI Feature Phone that has separate
PROGRAM and HELP keys, press PROGRAM.

The normal station programming menu
prompt will begin to play.

Stop the prompt by pressing HOLD (or, on an older ESI phone,
PARK).

Press 4 5 6 and then #.

Note:

If this doesnít admit you to Administrator-level
programming (the phone display should show ADMINISTRATOR),
contact your System Administrator or ESI Reseller for assistance.

Access Function 14 by pressing 1 4.(If the system prompts you to press 1 to set time and date, do
so.)

Enter a new time using a twelve-hour format and then press #.

Example:

Enter 1 2 3 3 # for 12:33 or
3 1 5 # for 3:15 (note that you need no leading zero
for the time).

Select AM or PM by pressing a scroll key and then #.

When the date appears, either:

Press # to accept the currently displayed date as
correct;or

Enter a new date in an eight-digit format,
including leading zeroes, and then press # and hang up to
finish the entry.

This feature, when enabled, causes the phone
systemís real-time clock to adjust itself automatically for Daylight Saving
Time. The options are AUTO [enabled] and DISABLE (the latter
is best for counties or states that donít observe DST).

To set this feature:

On any ESI phone within the system, press PROG/HELP.

Note:

If using an ESI Feature Phone that has separate
PROGRAM and HELP keys, press PROGRAM.

The normal station programming menu
prompt will begin to play.

Stop the prompt by pressing HOLD (or, on an older ESI phone,
PARK).

Press 4 5 6 and then #.

Note:

If this doesnít admit you to Administrator-level
programming, contact your System Administrator or ESI Reseller for
assistance.

Access Function 142 by pressing 1 4 2 and then #.

The phone display will show AUTO TIME SET, and either
ENABLED or DISABLED. If necessary, use the phoneís scroll
keys to toggle between the two settings. We recommend the ENABLED
setting.
When the display shows the setting you want, press #.

The phone display will now show DAYLIGHT SAVING, and either
AUTO or DISABLED. If necessary, use the phoneís scroll keys
to toggle between the two settings.
If you want your phone system to adjust its clock setting automatically
whenever your time changes between Daylight Saving Time and Standard Time
(either direction), select AUTO. If you live in an area which
doesnít observe Daylight Saving Time, select DISABLED.
When the display shows the setting you want, press # # and hang up.
